New bitcoins are created everyday.
But where do new bitcoins come from?
We will explain it simply.
To understand where bitcoins come from, let’s first look at where gold comes from.
Gold is mined from the ground.
There is no new gold created.
Rather, all gold already exists, it’s just mostly under the ground and not mined yet.
Gold miners find where gold is underground, build mining facilities at these locations, and use powerful machinery to extract gold from the ground.

The main point to understand here is this:
Gold miners don’t create gold, they simply bring gold from below the ground to above ground and this is called “mining”.
Bitcoin mining works similar to gold mining.
The amount of bitcoins that will ever exist is already determined in the software. There can only ever be 21 million bitcoins.
So what are Bitcoin miners doing?
Bitcoin miners are simply activating bitcoins as is set in Bitcoin’s code.
Just like gold miners are simply brining already existing gold above ground, Bitcoin miners are just “activating” bitcoins that are already scheduled in the code but not activated yet.
The Bitcoin code set it so that new bitcoins are released on average every 10 minutes.
Here is what a Bitcoin mining operation looks like (this is Hut8 Mining):
Let’s go back to gold to understand who gets new bitcoins.
With gold, a miner must find gold under the ground, go to the spot, and put mining machines there to mine the gold.
With Bitcoin, it’s similar but instead of physical mining the Bitcoin network requires you to use powerful computers to “mine”.
This is what a Bitcoin mine might look like:
Bitcoin miners use powerful computers to mine, which also secures the network.
As a reward for providing security, the miners are rewarded with new bitcoins if the find a new block.
What is a new block?
Every 10 minutes, one miner will be given the reward of new bitcoins. This is called finding a “block”.
Miners compete with computing power and will be rewarded at the level of their computing power.
For example:
If a miner has 1% of all Bitcoin computing power, that means they would expect to get 1% of all new bitcoins.
So, you may be asking:
If I buy bitcoins on an exchange, where are those bitcoins coming from?
Well, all bitcoins were originally mined by Bitcoin miners. After they are mined, miners can sell the bitcoins to whoever they want.
Most miners sell some of their Bitcoin after its mined to pay for the electricity used to power their mining machines.
